This sample does not work in Windows 7 with IE 8 because of UAC restrictions.

I can't say to users to run as administrators. Any workaround?

Thanks

Hi Anish Sharma,

The SaveFileDialog's purpose is to download files and save them to user's computer. It's not for uploading files.

Balupad, this seems to be impossible in the current release but we can expect the guys from Microsoft to add this feature in future releases.

Hi Didier,

Here I uploaded the complete source project for this demo:

FileSaveDialogDemo.zip

You need to create your own service and update the service reference in the ServiceReferences.ClientConfig file. The project contains exemplary web service which you may modify and use.

SilverlightShow editor: The source code has been added to the article.

RE: Using the SaveFileDialog in Silverlight 3

Didier — Sun, 15 Nov 2009 21:35:03 GMT

This is a great article and exactly what I was looking for. I embedded the code in my silverlight 3 / expression Blend app. I am able to see the file dialog. However, I can not get the code to create the file. I am unable to find the reference to FilesServiceReference. Where can I find the DLL for this reference?

Thanks in advance for your help,

Didier

Thank you very much for all your help. It is greatly appreciated and I have successfully used SaveFileDialog.

Hi again, sltester,

That's what I am doing in the service:

    
            [OperationContract]  
        
            public byte[] GetFile()  
        
            {  
        
                return File.ReadAllBytes( HttpContext.Current.Server.MapPath( "~/Files/text.zip" ) );  
        
            }

Thank you for your response nikolay, I have accomplished zipping the files but am still lost on what to do with my zipped file and SaveFileDialog. I have put multiple files into my zipped file using a "ZipFileStream" in my web service, do I return the "ZipFileStream" or the whole file? and then I would use e.Result as byte correct?

RE: Using the SaveFileDialog in Silverlight 3

nikolayraychev — Thu, 23 Jul 2009 09:56:18 GMT

sltester, the technique is the same with the zip file. It's about service implementation how you will put your files in a zip archive but it is beyond the scope of this article.

RE: Using the SaveFileDialog in Silverlight 3

sltester — Wed, 22 Jul 2009 21:04:18 GMT

Do you know of a way to do this with a .zip file? I am trying to zip multiple files in my webservice and return it to my Silverlight Web App to use the save file dialog. I believe this is the best way to handle saving multiple files to the user's machine. Am I correct

Yes, it is a text file.

Thanks for your comment Todd, can you please give a tip how we can save the element tree to an image. I was playing with the WriteableBitmap but did not find any solution.

RE: Using the SaveFileDialog in Silverlight 3

Todd — Fri, 17 Apr 2009 22:59:14 GMT

Silverlight 3 contains Bitmap APIs that WILL allow you to save the element tree to an image.

nikolayraychev — Mon, 06 Apr 2009 08:41:16 GMT

George, I think that Braulio is right. I did not find solution for saving the content of a Canvas directy as an image. There is a kind of workaround where you send the XAML to a service and on the server you use WPF to convert it to an image and after that the service returns the image. But that's an ugly workaround beacuse another round trip to the server is needed.

RE: Using the SaveFileDialog in Silverlight 3

Braulio (dbschemaeditor.com) — Fri, 03 Apr 2009 15:24:46 GMT

Jeje the canvas save is something quite demand on SL2 (the only workaround available was to port all your drawing code to GDI+ and perform that render in the server).

Until now I haven't read anything about saving canvas or exporting to image on SL3, let's hope the implement something (I think it's a must).

Nice article. Sometimes, if I press the Escape key, or close the browser window while uploading images in Silverlight, I can see that half of the image is uploaded, and the rest is cut off. I can see the half image when I open it next time.
